I've been collecting wands when I can afford to do so, which isn't much of the time, but here's my collection. It's a mix of the Noble mystery wands, a light-up Harry Potter wand, an interactive WWOHP Snape wand, and the Noble Collection Dumbledore and Voldemort wands.

For those of you who are curious about how the Noble Mystery wands compare to the Noble Collections wands, here's some comparison images and info.
Harry Potter Light-up vs Noble Mystery: The wood look on Harry's wand is great and is more realistic than the light-up version. The coloring along the shaft seems a tad darker than it should be, but still great.
Snape Interactive WWOHP vs Noble Mystery: The intricate design on the handle isn't etched quite as deep on the Mystery wand but it is still very clear.
Voldemort Noble Collection vs Noble Mystery: The Mystery wand has more of a matte look than it's more expensive counterpart and is lighter in coloring. The black spots aren't shaded around them to make it look naturally-occurring and come off looking a bit odd when inspected up close.
Dumbledore Noble Collection vs Noble Mystery: The Mystery wand reduces the length by shortening the distance between the bumps along the shaft, which ends up making it look kinda like a stubby re-imagining of the wand rather than a recreation. The indention spots on the bumps and on the handle are done extremely well and look much like the Collection version.
The Noble mystery wands are a MUCH sturdier material and are made to be either played with or displayed. Better option for kids to handle, definitely. They are slightly fatter and smaller than other wands because they're all made to be the same length, but still have pretty good quality for the most part. The attempt at a wood-grain look on Tonks and Krum's wands don't look realistic and appear more like streaks painted on. Overall I think the Noble Mystery wands are definitely worth getting if you want something you can handle regularly or for a version you can use with cosplay. Because they do appear to be entirely made of PVC, I wouldn't suggest using them in displays which could potentially bend them though.
